Looking for original 383 block for my 69 Dart


I have a 69 Dodge Dart GTS, 4 speed. I am looking for the original 383 block for this car. The VIN number is LS23H9B203175. The car came out of CT. I have fender tag, VIN number on dash and complete Broadcast Sheet and would like to find the block and transmission to complete this car. If anyone has any information please PM me.

Thanks,
